29g Biocube interior dimensions?

[dcfluegel]

Quick question for any 29g Oceanic Biocube owners - what are the dimensions of the tank vs 'sump' area? I know that basic footprint is approximately 20.5" x 20.5" but I am trying to track down some specs on how much room the back area takes up and what the actual footprint inside the 'display area' would be... halp?

20" wide x 16" long + 4" back filter area (20" long total).
